Indeed! I agree.
Wouldn't totally solve the problem. But it would help a lot.
My general position is that mating in a dense/urban environment is much more complicated than it is in more agrarian settings when dealing with a much smaller population and few eligible mates. And that the need for date training becomes greater the greater the complexity of a society and its sexual/romantic interactions.
I guess the one snag is if you instantly made every guy good with girls, you'd be right back at square one. And would have to devise new, alternate methods to get them, since "good game" is basically just a competitive advantage over men who don't have it. As soon as every guy has it, you get a bunch of needy men again, who will do needy things. Guys with good game can become quite needy if every other guy in the vicinity has good game too.
